What Happened to Battlefield Air Interdiction?

Colonel McCaffrey traces air-ground doctrine and operational practices relative to battlefield interdiction from World War I to Operation Desert Storm and suggests at one point that even the flank support for General Patton was, in effect, battlefield air interdiction (BAI). He carries the discussion through the decade after Desert Storm and shows how the issue is too important to be dropped by the Air Force and Army, even as technology provides new weapons for both services. Colonel McCaffrey concludes that there is still need for a BAI-type mission. Both services are searching for an answer to the doctrinal void.
